What is the structure of YRT rotary table bearing?

YRT rotary table bearing is a kind of high load rotary locating bearing. Its structure mainly consists of bearing outer ring, inner ring, ground ring and two sets of axial preload device. The inner and outer rings are separated by balls to restrain the balls from rotating with the inner and outer rings. The function of the ground ring is to stabilize the bearing and prevent the bearing from deformation. The two sets of axial preload devices can ensure axial stability.YRT rotary table bearings are simple in structure, and are mainly characterized by high loads, high-precision positioning and very high speeds, and are therefore widely used in CNC machine tools, medical equipment and other fields.
